Abstract

We have implemented an object-oriented real-time database system called BeeHive. Using BeeHive, the performance of two data-deadline cognizant scheduling policies', called EDDF and EDF-DC, and a baseline EDF policy all with/without admission control are evaluated through extensive experiments'. We identify the ranges where data-deadline cognizant scheduling policies are effective. We also show that when admission control is used it plays a more significant role than slecialized real-time data cognizant policies. Our admission control policy considers' not only CPU utilizations', but also I/0 requirements' and utilizations. These results' represent one of the few sets' of experimental results' found for an implemented real-time database; almost all previous results' are via simulation.
